BARdesc BAR_new | ( | int | N, |
int | M, | ||
int | W | ||
) |
Creates a BAR whose matrix size is N-by-M, with beam width W.
N | First dimension size for the new matrix (see BARdesc). |
M | Second dimension size for the new matrix (see BARdesc). |
W | Beam width size for the new matrix (see BARdesc). |

int BAR_read | ( | BARdesc | BAR, |
int | x, | ||
int | y | ||
) |
Reads a single integer value from the specified cell of the matrix in a BAR.
Usage:
i = A(x,y)
is expressed as
i = BAR_read(BAR, x, y);
BAR | BAR descriptor: the matrix we want to read from. |
x | matrix x coordinate of the value we want. |
y | matrix y coordinate of the value we want. |

void BAR_reinit | ( | BARdesc | BAR, |
int | N, | ||
int | M, | ||
int | W | ||
) |
Changes the size of a BAR (erasing the contents of the BAR).
This function must never be passed a NULL object.
BAR | The BAR to resize. |
N | First dimension of the new size of matrix (see BARdesc). |
M | Second dimension of the new size of matrix (see BARdesc). |
W | Beam width of the new size of matrix (see BARdesc). |

void BAR_write | ( | BARdesc | BAR, |
int | x, | ||
int | y, | ||
int | i | ||
) |
Sets an element of a BAR.
Usage:
BAR_write(BAR, x, y, i);
sets A(x,y) = i.
BAR | BAR descriptor: the matrix we want to write to. |
x | matrix x coordinate of the cell we want to write in. |
y | matrix y coordinate of the cell we want to write in. |
i | value to set it to |
